SCREW DRIVER AND HOLDER.

SPECIFICATION forming part of Letters Patent No. 689,722, dated December 24, 1901. Application mea May 6, 1901. sert-l1 No. 58,995. oto model.)

To @ZZ whom if; may concern:

Be it known that I, FRANKLIN HOOVER, a citizen of the United States, residing at Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvementsin Screw Drivers and Holders, of which the following is a specification, reference being had therein to the accompa nying drawings.

The invention has reference to a combined screw driver and holder particularly designed for use in the construction or repair of pianos, where the screws to be inserted or withdrawn are usually located in places inaccessible to the hand of the operator.

The invention consists in the novel construction ot' a tool and in the peculiararrangement and combination of its parts, as hereinatter described, and shown in the drawings, in which- .Figure 1 is a view in elevation of the improved tool. Fig. 2 is a sectional elevation thereof. Fig. 3 is aviewin section of the outer end of the tool, and Fig. 4 is a perspective View of the outer end ofthe tool.

The reference-letter A designates a shank cylindrical in cross-section and having integral therewith and projecting from its outer end the spring-arms Band C. As shown, the arm B terminates i-n a screw-driving point E, while the complementary armis provided at its extreme outer end with an inwardly-facing jaw F. To enable the jaw to be inserted beneath the screw-head, it projects beyond the driving-point E a slight distance and is provided with an inclined offset portion G.

H designates an elongated sleeve, which in this particular case constitutes a handle for the tool and is corrugated, as at I, at its inner end, so as to enable the operator to obtain a handhold thereon. The sleeve, as shown, engages the shank and spring-arms and is slidable thereon, so as to permit of its forcing the spring-arms in proximity to each other for the purpose of gripping and holding the screw in the manner indicated in Fig. 3. In order that the sleeve may be used as a handle for operating the 'tool, a guide pin J is inserted through the outer end portion of the sleeve and between the Vspring-arms, as indicated in Fig. 2, the pin serving to limit the outward movement of the arms and also to prevent independent rotary movement of the latter relative to the sleeve.

In operation, the tool being in the position as shown in Fig. I, the screw being first loosened, so as to space the head, the operator inserts the tool between the parts of the action in which the screw is located and engages the driving-point in lthe slot in the head. The sleeve is ot' suiiicient length to permit of its being actuated by the operator and at the same time bear against the arms in proximity to their ends. The outward movement of the sleeve causes the jaw to move beneath the screw-head, and as the sleeve end reaches the inclined offset G the jaw is forced tightly in engagement with the screw, thus permitting the latter to be withdrawn and effectively preventing it from dropping within the instrument.

As a means of limiting the inward movement of the spring-arms I have provided a stop for the same adapted to strike against the outer jawK of the sleeve. vIn this case the stop is formed by a portion L of the inwardlyextending part of the jaw.

From the description of the ,invention as set forth it will be seen that the combined driver and holder is so formed as to produce a tool of rigid construction capable 0f removing or inserting the screws and of effectively preventing their being detached from the driver. It is also obvious that in View of its simplicity of construction the cost of manufacture will be considerably reduced.

What I claim as my invention is I. In a screw driver and holder, the combination with two complementary spring-arms, a screw-driving point and an inwardly-facing jaw upon the outer ends of said arms, and an elongated sleeve slidable on said arms.

. 2. In a screw driver and holder, the combination with a shank member, f two complementary spring-arms extending from one end ofthe shank, a screw-driving point and an inwardly-facing jaw upon the outer end of the arms, the jaw projecting slightly beyond the point, and an elongated sleeve slidable on the shank and arms.
